固定菜单不适用于当前下拉菜单

Question

当您将鼠标悬停在“治疗”上时，我创建了一个带有下拉功能的菜单。但是，当我申请“职位：固定;”在CSS上的容器类中，下拉菜单不再起作用。菜单进入固定位置，但下拉功能无法在固定位置运行。我想用CSS解决它，有关如何的任何建议？

CustomCell

.container {
  overflow: hidden;
  background-color: rgba(48, 48, 48, 0.9);
  font-family: Helvetica, sans-serif;
  width: 100%;
  position: fixed;
  margin-top: 0;
  margin-left: 0;
}

.container a {
  float: right;
  font-size: 16px;
  color: white;
  text-align: center;
  padding: 14px 16px;
  text-decoration: none;
}

.dropdown {
  float: right;
  overflow: hidden;
}

.dropdown .dropbtn {
  font-size: 16px;
  border: none;
  outline: none;
  color: white;
  padding: 14px 16px;
  background-color: inherit;
}

.container a:hover,
.dropdown:hover .dropbtn {
  background-color: #ff008f;
}

.dropdown-content {
  display: none;
  position: absolute;
  background-color: rgba(255, 255, 255, 0.98);
  min-width: 160px;
  box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2);
  z-index: 1;
}

.dropdown-content a {
  float: none;
  color: black;
  padding: 12px 16px;
  text-decoration: none;
  display: block;
  text-align: left;
}

.dropdown-content a:hover {
  background-color: #f9e9ff;
}

.dropdown:hover .dropdown-content {
  display: block;
}

overflow: hidden元素上的.container阻止下拉菜单显示 - 而不是position: fixed。通过隐藏溢出，您可以防止超出.container尺寸的元素（例如您的下拉菜单）显示。

＆＃13;

.container {
  /* overflow: hidden; */
  background-color: rgba(48, 48, 48, 0.9);
  font-family: Helvetica, sans-serif;
  width: 100%;
  position: fixed;
  margin-top: 0;
  margin-left: 0;
}

.container a {
  float: right;
  font-size: 16px;
  color: white;
  text-align: center;
  padding: 14px 16px;
  text-decoration: none;
}

.dropdown {
  float: right;
  overflow: hidden;
}

.dropdown .dropbtn {
  font-size: 16px;
  border: none;
  outline: none;
  color: white;
  padding: 14px 16px;
  background-color: inherit;
}

.container a:hover,
.dropdown:hover .dropbtn {
  background-color: #ff008f;
}

.dropdown-content {
  display: none;
  position: absolute;
  background-color: rgba(255, 255, 255, 0.98);
  min-width: 160px;
  box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2);
  z-index: 1;
}

.dropdown-content a {
  float: none;
  color: black;
  padding: 12px 16px;
  text-decoration: none;
  display: block;
  text-align: left;
}

.dropdown-content a:hover {
  background-color: #f9e9ff;
}

.dropdown:hover .dropdown-content {
  display: block;
}
